MAX9719BEUE+T

Audio Amplifiers Overview

The MAX9719BEUE+T is a dual-channel Class AB audio power amplifier in a 16-pin TSSOP-EP package. It operates on a single supply from 2.7V to 5.5V and delivers 1.4W continuous average power per channel into a 4Ω load with less than 1% THD+N at 5V. The device features differential inputs, internally fixed gain of 0dB, and a low-power shutdown mode reducing current to under 1μA. It includes click-and-pop suppression and thermal protection.

Audio Amplifiers Feature Summary

• Bridge-tied load (BTL) architecture for high-quality audio amplification
• Integrated click-and-pop suppression circuitry
• Low-power shutdown mode with configurable polarity options
• Internally fixed gain configuration to minimize external components

Audio Amplifiers Applications

• Mobile phones
• Personal digital assistants (PDAs)
• Portable audio devices

Audio Amplifiers Procurement Notes

Verify the specific suffix +T indicates tape-and-reel packaging when sourcing. Confirm the BEUE designation corresponds to the 16-pin TSSOP-EP package variant. Ensure compatibility with the required 0dB fixed gain specification. Check for lead-free/RoHS compliance status as indicated by the plus sign in the part number.

Audio Amplifiers Selection Notes

Select this component for stereo applications requiring differential input noise rejection. Choose the fixed 0dB gain version if external feedback resistors are undesirable. Consider the TSSOP-EP package for its exposed pad thermal dissipation capabilities. Verify that the 2.7V to 5.5V supply range matches the system design constraints.

Audio Amplifiers Part Context

This part belongs to the MAX9718/MAX9719 family of low-cost mono and stereo audio amplifiers. The MAX9719 specifically provides dual-channel output for stereo systems. It serves as an upgrade path for designs previously using LM4895 amplifiers, offering improved performance and pin compatibility within the same functional category.

Audio Amplifiers Replacement Considerations

The MAX9718 series is pin-compatible with the LM4895. For direct replacements within the same family, consider other MAX9719 variants with different gain settings or packages, such as MAX9719BETE+T (TQFN) or MAX9719BELE+T (UCSP), provided the gain and interface requirements align.
